RAILWAY-TRACK SANDER. 1 i

Application led July 2,

This .invention relates to track sanders adapted to be attached to locomotives and other railway cars and having a compressed air discharge nozzle operatively controlled from the cab from the locomotive, with said nozzle arranged within the sand discharge pipe whereby to blow the sand from the sandbox through said pipe and deposit the same on the car rails.

An important feature of the invention is to provide for the mounting of the air nozzle within the sand box and at the same time provide means wherein the same may be easily reached from outside the sandbox in the event of clogging so as not to necessitate the removal of the sand from the box in order to clear the airline. An important advantage in locating the air discharge nozzle within the sandbox is that the same is not exposed to weather conditions which fret nently cause the clogging of such nozzles;

t at such nozzle is thereby protected from breakage by obstacles which the sander might come into contact with and provides for a more efficient and reliable device ofthis character.

A further object is to provide an air hose connection for a track sander which may be easily and quickly installed in operative position upon conventional types of sand boxes without necessitating any material changes in the construction thereof.

Other objects and advantages reside in the special, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein: y

Figure 1 is a vertical sectional view through a sand box showing my air nozzle in operative position therein, and,

Figure 2 is a sectional view taken along a line 2--2 of Figure 1.

Referring now to the drawing the invention is shown adapted for use in connection with a sand box for locomotives comprising a housing of any suitable shape or construction through one wall of which is formed an opening adapted to receive a short pipe section 6 having its outer end internally threaded and within which is threadedly inserted a plug 7.

The plug is of hollow construction and provided with internally arranged threads 1927. Serial No: 203,208.

whereby to receive the threaded end of a nipple 8 extending outwardly of the plug and provided at its outer end with a threaded pipe T 9, said T having a discharge pipe 10 extending downwardly therefrom and arranged in position to discharge the same upon a railway track. A plug 11 may be fitted in the outer end of the pipe T.

An air duct indicated at l2 is arranged longitudinally at the upper side of the plug 7 connected at its outer end with an air pipe 13 extending to an air valve located in the cab of the locomotive, with the inner end of said duct terminating concentrically with the opening formed in the nipple 8, the inner end of said duct being provided with a plug 14 having a reduced opening extending therethrough to form a pressure discharge nozzle therein.

It is apparent from the forgoing explanation when considered in connection with the illustration of the device as shown in Figure 1 of the drawing that sand from the' housing or sand box 5 will be adapted to enter the inner end of the pipe 6 and will be discharged therefrom through the nipple 8 and discharge pipe 10 upon the admission of compressed air through the duct 12 and out of the nozzle 14. In this manner a positive means for discharging the sand upon the track is provided. Should any'foreign matter such as waste or cinders from the locomotive enter the discharge pipe 10 the same may be readily removed and cleared merely by unthreading the T and nipple from the plug 7 without interfering with the remainder of the device. Also should the air duct in the plug 7 become clogged the same may readily be cleared by disconnecting the air pipe 13 and removing the plug 7 from the pipe section 6. In this manner the entire parts constituting the invention may be removed for repair or replacement without necessitating the removal of the sand from the sand box.

It is obvious that the invention is susceptible to various changes and modifications without departing from the spirit thereof or the scope of the appended claim and claim is made to all such forms of the device.

What is claimed is:

In a track sander, a sand box having a pipe section extending within the same, said pipe section having its outer end internally threaded, a hollow plug threadedly arranged llu Within said pipe section having a sand disremovably carried at the discharge end of charge-passage formed longitudinally therethe air duct. 10 through, an inwardly disposed L-shaped ex- In testimony whereof, we aliix our signa tensionfornied on the plug with :u1 air duct tures.
